How do i redirect user to "home" controller after successfully loggin?

PHP Code:

I have this method for login
public function authenticate(){
//get formm input into an array
$login_data = array(
'username' =>$this->request->getPost("username"),
'password' =>$this->request->getPost("password")
);

try{
  if($this->model_login->login($login_data)){
//redirect(base_url('home')); 
  redirect('home'); 
}else{
  $data['error'] = 'Incorrect password/username entered';
  echo view('view_login', $data);
}
}catch(\Exception $e){
die($e->getMessage());
}
} 


When the user succesfully login it throws this message "{0, string} route cannot be found while reverse-routing" instead of redirecting to "Home: controller.
